Transformation: Transfer Function ↔ Signal Flow Graph

Given a system transfer function it is possible to derive a signal
flow graph directly, but it is more convenient to first find a space
model, and then move from the state space model to the signal flow graph.

Example: Transfer Function → Signal Flow Graph

Find a signal flow graph for the system described by the transfer
function:

Step 1: Find a state space representation using the
methods described here (TF ↔ SS). In this case we are using a CCF
form).
